Assembly of the mitotic spindle requires timely separation of the centrosomes. Their movement apart is driven by the plus-end-directed kinesin Eg5. A new study demonstrates that the kinesin KIFC3 provides an opposing microtubule-based cohesive force that modulates centrosome separation and ensures accurate chromosome segregation.
